Learning Objective
I can subtract two-digit numbers with regrouping.
- 1
When subtracting two-digit numbers, it is important to line up the ones and tens places correctly.
- 2
If the ones place in the top number is smaller than the ones place in the bottom number, you need to regroup or borrow from the tens place.
- 3
When you regroup, you take 10 from the tens place and add it to the ones place so you can subtract.
